Abstract : Since the -Plan Informatique Pour Tous- in 1985, digital technologies occupy an increasingly importance in education: digital textbooks, dynamic geometry software, learning games, e-learning, blended learning, MOOC, flipped classrooms, educational robotics, etc.The aim of our work is to show that some of these technologies can contribute to improve learning, boosting learning contents, emphasizing student motivation by proposing devices suitable for distance learning and personalizing learning paths.The stakes of these issues are important. The need to motivate students and personalize learning is more and more crucial. These are major assets to reduce dropout and promote equal opportunities.Objectives of our work before 2011:- Gamify contents to make them more motivating.- Visualize concepts by using digital objects.- Virtualize learning objects in order to reduce physical constraints to work methods, to overcome handling difficulties and disability situations.- Provide tools for interactivity, visualization, computer algebra and geometry for computer environments learning distance learning platforms, software.- Provide tools for monitoring user activity in order to better track their progress, to follow them with precision, to making them more autonomous.- Experiment with objects both digital and tangible such as robots, to assess their impact in learning.- Build new textbooks by accompanying them with digital devices.This work was continued in recent and more research-driven work.Objectives of our work from 2011:- Optimize and personalize learning by using artificial intelligence and machine learning algorithms.- Use tangible objects such as robots, that students can manipulate and program, to approach learning differently to provide concrete environment to build new concepts.
